Benefits of technology

The present invention provides a system selection method for mobile terminals that allows for efficient and stable system selection. The method includes configuring a system search table for system selection, registering various search scenarios, and performing system search based on the system search table. The method also allows for the mobile terminal to read system information from a Most Recently Used (MRU) table and a Preferred Roaming List Acquisition (PRL ACQ) table, and allocate an index to each piece of system information. The system search table can also be configured by setting areas and allocating repetition flags to the system information. The technical effects of the invention include improved system selection efficiency, flexibility, and stability of mobile communication services.

Problems solved by technology

In addition, when the developer desires to change the search order of the system scan list, he / she should know all processes for configuring the system scan list, making it difficult to change the search order.

Embodiment Construction

[0050] Exemplary embodiments of the present invention will now be described in detail with reference to the annexed drawings. In the following, detailed description of known functions and configurations has been omitted for clarity and conciseness.

[0051] According to the present invention, a mobile terminal configures a new search table instead of the existing scan list, and acquires a system through various search scenarios.

[0052] Referring to FIG. 3, according to the present invention system search table 380 introduces the concept of areas within the table. In the present invention, the areas defined in system search table 380 are classified into two types according to their attributes: one is a variable area 302 having a variable attribute and another includes fixed areas 304 and 306 having fixed attributes. The variable area 302 has a fixed maximum area value (end max=MAX1), and is divided into an in-use area 308 and a reserved area 310. Variable area 302 can undergo area upda...

Abstract

A method for selecting a system in a mobile terminal is disclosed. The method includes upon power-up of the mobile terminal, reading system information included in a Most Recently Used (MRU) table from memory, and registering the system information in a variable area of a system search table; reading system information from a Preferred Roaming List Acquisition (PRL ACQ) table stored in the memory, and registering the system information in a fixed area of the system search table; and performing system search based on the system search table.

Description

PRIORITY [0001] This application claims priority under 35 U.S.C. § 119(a) to a Korean Patent Application filed in the Korean Intellectual Property Office on Mar. 9, 2006 and assigned Serial No. 2006-22388, the disclosure of which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates generally to a method for accessing a mobile communication system by a mobile terminal, and in particular, to a method for selecting a system by a mobile terminal. [0004] 2. Description of the Related Art [0005] To cope with the rapid development of mobile communication systems and the large increase in the amount of data being serviced in the mobile communication systems, 3rd Generation (3G) mobile communication systems with the necessary throughput for transmitting the increased amount of data at higher speed have been developed. For the 3G mobile communication systems, Europe has adopted asynchronous Wideband-Code Divisio...
